I don't know if you will read this at this late date, but I am curious about the cerebral bypass that was performed on your daughter. It has been mentioned to me by several doctors that this might be a consideration for me. But my primary neurologist says that these bypasses were abandoned in the 80's and that they don't work. Maybe this is why your daughter is having so much trouble. I am going to see a world famous neurosurgeon next week regarding this very subject. I certainly wish you well!
